Hi - can anyone in Cape Town recommend a decent ISP that doesn't unnecessarily route traffic through JINX or similar, but rather sticks to keeping routing local?

What do you mean by routing through JINX unnecessarily? Do you have an example?

Some ISP's like Cell C send all their CPT traffic to JHB and then pick it up there and route from JHB

Fair enough... There are extreme examples like
Cell C - which btw makes no sense given their full routing core in CPT (they have quite an impressive HUAWEI setup). But OP was pretty specific about JINX- so wondering if he’s currently stuck routing to JHB by default or unnecessarily (maybe poor routing). This is where a looking glass is useful.

Vox for a few months were doing this as well sending all Vumatel and Openserve traffic to JHB and then sending it via ESSY, I've heard of a few others doing this as well... They use excuses like "WACS is oversubscribed and thus it results in higher pings and extreme packet loss"...

Well for example I have a colleague on CISP - we both connect to the same VPN for work, his ping to our server is around 6ms mine is upward on 30ms on a good day. On a prior ISP I had no issue, on my current one I do have an issue. We both ran some traces and the big thing is high ping for me when traffic is routed up to JHB while his stays in CPT. Might just add I’ve asked my ISP to look into this previously and it seems something was changed, but it’s now back through JHB (JINX) again. I could barely work when on the VPN, after the change it was fine, now it’s slow again. Already in notice period so looking for a new ISP at this stage. CISP looking promising right now!

I don't want to fish for details just hoping we did not drop the ball here. If we did want to fix it asap. :)

Would be interesting to see the traceroute from you and your colleague. It seems your ISP does route out of Cape Town if they could preciously fix this, however a few possibilities exist here. Your isp isn’t selecting routes correctly (IE it’s preferring it’s joburg learnt routes over the ones in CPT- more likely) or, the network you’re connecting to is dropping its advertisements in CPT (less likely). Or finally, your ISP is advertising incorrectly on the two exchanges (30ms sounds like asymmetric routing).

I'm not sure if Vox peers with route servers so is possible RSAWeb havent setup bilateral peering, something they should be able to resolve quite easily.

The problem is it's pretty much impossible to get in touch with anyone there or get a response to tickets at the moment (I got a reply to a ticket yesterday that I raised about 2/3 weeks ago)... And like I said before, my service is ending 31 July, so they might not really care at this stage anyway ;)
 
I knew this would be Vox :ROFL: Vox has a lot of routing issues...

Some of the stuff i have seen from friends and on the DSL thread just make me shake my head...

Like going to Angola then New York then London then finally France...

I'm not with Vox, though, (and neither is my colleague) and me and him are both tracing to the same IP?

Not really Vox's issue here, more RSAWebs.
